How Real Is Your Money?

If a tree falls in a forest,
and no one is there to hear it,
is there a sound?

Is sound not sound
only when there is a hearer,
who thus defines it as sound?

If your money in a bank
is just a virtual number,
is there any real value?

Gathering interest aside,
is the money really your money
when it is not being used by you?

Is money not your money
only when you are the user,
which thus defines it as your money?
